B e 1t known that I, PAUL JAMNITZKY, a subJect of the King.

This inventionrelates to propeller mechanisms for air ships, aeroplanes and simiiar heavier-than-air machines.'

The primary object of my invention is to propel an air ship upon the principle of a iiylused for this mg bird, a plurality of wing blades being purpose, which are driven by a motor located in the body of the machine.

Another object of my invention is to provide novel Wing blades for pocketing air upon a down stroke and allowing air to pass directly through the blades onan up stroke,

scribed and claimed. y

thereby obtaining a maximum degree of efyiiciency for elevating purposes with a minimum expenditurepf fuel and retardation by air pressure when elevating the blades.

A further object of my invention is to provide an air ship with oscillating wing blades that can beused upon the principle of a parachute for allowing the air shi i. to gradually descend should an accident happen to the drivin power of the air ship.

Wit the above and other objects in view which Will more readily appear as the inventionis better understood, the same consists inthe novel construction, combination and arrangement of parts to be presently de- In the drawings :-'l `igure 1 is a diagrammatic yview of the endof an air ship constructed in accordance with my invention, Fig. 2 is a diagrammatic plan of the same, Fior. 3 is a plan of one of the blades, Fig. 4 is a longitudinal sectional view of the same, Fig. 5 is a cross sectional view of the same with the Wings 'in an open position, Fig: 6 is a similar view, partly broken away, with the wings in .a closed position, Fig. 7 is a sectional detail of a' blade frame member also showin a wing attached thereto, the wing b'eingi ustrated in full and in dotted lines.

f In the accompanying drawin s, l have n ofHurigary, residing at y Conemalgh, In the county of Cambria andy' ennsylvama, have invented certain provided with a suitable rudder 4 'by which the lateral direction of the air ship can be controlled.

Upon the latforxn 1 is-located a motor or engine 5 an bearings for the longitudinal shaft 7 driven by said meter or engine. Ad-

9 for shafts 8, said shafts together with the shafts 7 -bein provided 'with small belt wheels 10 and irge belt Wheels 11, by which the shafts are driven in unison through the medium of belts 12 placed upon said small and large belt wheel s Pivotall connected to the standards 2, as at 13, are lre vends thereof provided-With pitmen 16 which are eccentrically connected to the large belt wheels 11, whereby a rotary movement ol said belt whe/els will oscillate the levers 14 and 15, i

Secured to the outer ends of the levers 14 and 15 are 'wing blades, said blades in plan being oval and in central cross section semigradually decreasing toward lthe ends thereof. Each blade.' comprises a transverse arches 17 and a plura it of longitudinal frames 18 which are equally spaced apart and Xed in the" under sides of the arches 17. The'ends of the archesl and the frames 18 are connected by an oval frame 19. The frames 18 are triangularshaped in cross section, and pivotal] r. connected to said frames are a. plurality o wings 20, said wings corresponding in length to the distance between the arches 17, and in width to the distance between the framesA 1S, whereby said wings in the closed position will entirely close the spaces between the arches j 17 and the frames 18. .In order that thel rj wings 2() will all swing in the V'same direction ,l when closing, the frames 18 are formed with i shoulders 21 against which the wings rest in an open position. 'The lower edges of the whereby the wings between cach set of arches 17` will close in unison.

Referring to Fig. 1 of the drawings, ,it will be observed that diagonall disposed blades are in similar positions, 'an it is through this arrangement of the blades, when in 'operation, that I am enabled to maintain the equilibrium of the flying air ship. When one of the `blades ascends, the air rushing through the frame-work of each blade maintains the blades 20 in an open position, as shown in vers 14 and L5 having the inner circular, the cross sectional area of the blades lurality of jacent to the bearing 6 are arranged bearings wings are connected together by cables 22 y frame, oscillatory levers supported y and contrivances., I have illustrated the -same diagrammatically and ,reserve the right to cillator'y Wing blades, the Wing blades of one -tion with air ships, aeroplanes, iiying' ma-4 -ternately disposed with respect to theblades 'pivotally connected tds'aid -frames ,and

alinement'with respect 'to 'the wings of the E il e l920,064v

Fig. 5, but when a blade descends, the wings vY otheri set, and a cable connecting the wings of 20 immediately close, and as each blade is of a each set together whereby the wings of each large area, the blades impacting against the 'set' will close in unison.v air will lcause the air ship to rise. Y2. Anr'air-ship comprising a supporting The -rectangular skeleton frame, together frame, oscillatory levers carried thereby, an with the blades can be constructed of bainoval-shaped wing blade connected to the boo, aluminum or similar light a'r'idfdurablev outer. end of. said levers, each of said Wing material, and the,v wings 20- can be made' of l blades comprising `transversely extending reinforced sheets of fiber. v arches, frames connecting said arches vand My air ship is' particularly designed for observation, also for traveling and alLcoml provided witha stop, andsets of transversely mercial purposes growing out of its future extending wings pivotally connected to said `development and any suitable-means of conframes and adapted to close .the spaces betrol can be ,used in connection with the same. tween said arches and said-frames, saidfwin'gs Due to the fact that vny invention can be l having their movement limited in one direcused in connection with various kinds of air tion b y saidfstops.v I 3.
